India has tested a ballistic missile capable of carrying a nuclear warhead up to 5,000 kilometres (3,100 miles), the defence ministry said, in what media called a "stern signal" to China as the two remain locked in a border spat. The Agni-5 missile blasted off from Abdul Kalam Island off India's east coast late Wednesday and splashed into the Bay of Bengal. "The successful test … is in line with India's stated policy to have 'credible minimum deterrence' that underpins the commitment to 'No First Use' [of nuclear weapons]," a defence ministry statement said. The 17-metre-tall missile has been tested several times before, but not at night, and local media said that the timing was aimed at sending a signal to Beijing. Tensions with China have been running high since 20 Indian soldiers died in clashes on their disputed Himalayas border in June 2020.

India has deepened defence cooperation with Western countries in recent years, including in the Quad alliance with the United States, Japan and Australia. New Delhi is also a major buyer of Russian military hardware, and ordered Moscow's S-400 missile defence system despite the threat of US sanctions over the $5.4 billion deal. The Financial Times reported this month that China had tested a hypersonic missile that circled the Earth at low orbit before descending toward, but missing, its target. Beijing denied the report, insisting it was a routine test of a reusable space vehicle. Hypersonics are the new frontier in missile technology, because they fly lower and are harder to detect than ballistic missiles, can reach targets more quickly, and are maneuverable.
